USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
The Power Wave / Power Feed are best diagnosed
®
as a system. Each component (power source, user
interface, and feed head) has a status light, and when
a problem occurs it is important to note the condition
of each. In addition, errors displayed on the user
interface in most cases indicate only that a problem
exists in the power source, not what the problem may
be. Therefore, prior to cycling power to the sys-
tem, check the power source status light for error
sequences as noted below. This is especially
important if the user interface displays "Err 006"
or "Err 100".

Status LED is solid green (no blinking)

TROUBLESHOOTING AND REPAIR
POWER WAVE
Included in this section is information about the power
source Status LED, and some basic troubleshooting
charts for both machine and weld performance.
The STATUS LIGHT is a two color light that indicates
system errors. Normal operation is a steady green
light. Error conditions are indicated in the following
chart.
NOTE: The POWER WAVE
will flash green, and sometimes red and green, for up
to one minute when the machine is first turned on.
This is a normal situation as the machine goes
through a self test at power up.
INDICATION
1. System OK. Power source communicating nor-
mally with wire feeder and its components.
2. Occurs during a reset, and indicates the
POWER WAVE 355M/405M is mapping (identi-
®
fying) each component in the system. Normal
for first 1-10 seconds after power is turned on,
or if the system configuration is changed during
operation.
3. Non-recoverable system fault. If the PS Status
light is flashing any combination of red and
green, errors are present in the POWER WAVE
355M/405M. Read the error code before the
machine is turned off.
Error Code interpretation through the Status
light is detailed in the Service Manual.
Individual code digits are flashed in red with a
long pause between digits. The codes will be
separated by a green light. There may be more
than one error code indicated.
To clear the error, turn power source off, and
back on to reset.
Non-recoverable hardware fault. Generally indi-
cates nothing is connected to the POWER
WAVE ® 355M/405M wire feeder receptacle.
